Question

I will award you! :)

The vertex of a parabola is at (-2,4), and the x-intercepts are at -6 and 2. Determine the domain and range of the function.

a. D: all real numbers
R: all real numbers
b. D: -6 ≤ x ≤ 2
R: y ≤ 4
c. D: all real numbers
R: y ≤ 4
d. D: x ≤ 4
R: all real numbers

Answer 1

The domain should include all real numbers. Since x can go from positive infinity and negative infinity and you will always get a corresponding y value. The y is <= 4. If you graph the parabola, you will see that it points downward. Parabolas are infinite but they only grow in one direction. So any number below 4 is viable.

Answer 2

so c?:0
